Rewrite the equation in slope-intercept form:

9x - 7y = 21

-7y = -9x + 21

y = (9/7)(x) - 3

The y-intercept is where x = 0.

y = (9/7)(0) - 3

y = 0 - 3

y = -3

The x-intercept is where y = 0.

0 = (9/7)(x) - 3

3 = (9/7)(x)

21 = 9x

x = 21/9

x = 7/3

The correct answer would be C. The x-intercept would be at (7/3, 0) and the y-intercept at (0, -3). Hope that helps! :)

Decide which project the most profitable is by:
Doss [256]

Answer:

Project A :

NPV : $703,888.64

IRR : 44.882%

Project B:

NPV : $5,241.26

IRR : 49.662%

Project B is more profitable

Step-by-step explanation:

The NPV gives the difference between the present value of cash inflow and cash outflow over a certain period of time.

The Internal rate of return is the discount rate which makes the NPV of an investment 0. It is used to estimate the potential return on an investment. Investments with higher IRR are said to be better than those with lower IRR value.

Using the net present value, (NPV) Calculator, the NPV for project A is : $703,888.64

The IRR of project A is : 44.882%

The NPV for Project B is : $5,241.26

The Internal rate of return (IRR) : 49.662%

From the Internal rate of return value obtained, we can conclude that, project B is more profitable as it has a higher IRR than project A.

Jalil and Victoria are each asked to solve the equation ax – c = bx + d for x. Jalil says it is not possible to isolate x becaus
marishachu [46]

Answer:

x = \frac{c+d}{a-b}

Step-by-step explanation:

Given

ax - c = bx + d ( collect the terms in x together )

Subtract bx from both sides

ax - bx - c = d ( add c to both sides )

ax - bx = c + d ← factor out x from each term on the left side

x(a - b) = c + d ← divide both sides by (a - b )

x = \frac{c+d}{a-b}

NEEEEEEEEEEEEEEEEEEEDDDDDDDD HELP
Makovka662 [10]

Answer:

Step-by-step explanation:

1.

19² = 17² +x²

19² - 17² = x²

√361-289 =x

√72 = 8.5 ≈ x

Area = base*h/2 = 17*8.5/2 ≈ 72.3

Perimeter = 19+17+8.5= 44.5

and so on...

2.

x²= 5² +13²...

A= 5*13/2 =...

P= 5+13+x=...

3.

20² = 10² +x²...

A=10*x/2=...

P=20+10+x=...

4.

x² = 5² +14²...

A=5*14/2 =...

P= 5+14+x = ...
